Hey guys, I've enabled a few cool features on the site that you might wan to check out. Firstly there is the enhanced image uploader. This flash based uploader makes it easier to upload a large number of photos at once or even attach photos you uploaded in the past.
You can enable/disable the enhanced image uploader in your profile under general settings, it's near the very bottom. Give it a shot you might like it!
Another thing made easier with the enhanced image uploader is adding photos to groups and user albums. All registered users can create their own custom groups and albums, as an example I create some.
